K90 linear actuators from Exlar
(Chanhassen, MN) are compact, 90-mm
frame size actuators available in three
performance levels, and allow the use of
third-party motors. Featuring dimensions
and form-factor consistent with ISO
Metric pneumatic cylinder specifications, the actuators are designed to
provide a universal solution for linear motion rod-style actuator applications.
Three models offer two grades of roller screws and one Acme screw.
KX90 actuators incorporate a high-performance planetary roller screw for
applications in industrial automation, mobile equipment, process control,
and other applications requiring millions of inches of travel under load.

NITRA™ E-Series pneumatic dual-rod
guided air cylinders from Automation -
Direct (Cumming, GA) are designed for
applications that require precise alignment
or have large side loads. The devices
are interchangeable with other popular
brands of cylinders. The double-acting cylinders are constructed with
extruded aluminum housing and switch mounting tracks, dual chromeplated
stainless steel guide rods, and bronze bushings. The cylinders feature
a maximum operating pressure of 142 psi, and are available in eight
bore sizes from 12 to 63 mm. Available stroke lengths range from 10 to
250 mm, depending on bore size.

ASM Sensors (Elmhurst, IL) offers the PMIS4/PMIR5 non-contact
measuring system developed for rotary applications. The system provides
high EMC protection, large guiding distance tolerance, and signal
performance up to 327,680 pulses/360°. The incremental system
consists of a PMIS4 sensor
head and a PMIR5 incremental
magnetic ring. The sensor
head is made of a fully
enclosed, shielded metal
housing, offering protection
against electromagnetic interference
and thermal overload.
Guiding distance is ±1
mm. Available output types
are HTL, TTL, and TTL24V.

ADLINK Technology (San Jose, CA) has released the PCI-
8254/PCI-8258 motion controllers that provide servo updates up to
20 KHz through hardware-based PID-FF control loop and secondorder
filters, time-deterministic trajectory and velocity planning,
comprehensive application functions, and diagnostic and control
utilities. The program download function can execute up to eight
individual tasks simultaneously, providing control performance in
real time, and conserving
CPU resources. The controllers
also provide multidimensional
interpolation,
as in 3D linear/circular/spiral interpolation,
for contouring applications
in manufacturing
industries such as laser
engraving/cutting, glue
dispensing, and others.

Newport Corp.
(Irvine, CA), has
introduced the
FMSxxHA high-accuracy FMS stages for surface
metrology applications. The stages are
available in 100-, 200-, and 300-mm models.
With all-steel construction, the stages combine
high stiffness and thermal stability. The
crossed roller bearings have an anti-creep feature
to provide smooth and straight motion.
The steel ball screw is designed for highspeed
motion. The stages are driven by a stepper
motor, with a linear encoder that provides
on-axis accuracy down to 1μm and submicron
bidirectional repeatability.

Model LF series linear scales from HEIDENHAIN Corp. (Schaumburg, IL) are used on highaccuracy
machine tools, jig bore and grinding machines, and linear motors. The LF 485 and 185
incremental models feature very high repeatability and defined thermal expansion behavior.
From a grating period of 8 μm, the interferential scanning principle of the LF scales produces
scanning signals with a signal period of 4 μm. These scanning signals are largely free of harmonics
and can be interpolated. Accuracy grades to ±2 μm are possible. The scales also offer resistance
to contamination through the use of SUPRADUR steel scale tape together with a scanning
ASIC with large scanning window.

Kistler North America (Novi, MI) has
introduced the Kistler Type 9269A RoaDyn®
S6HT System 2000, a six-component wheel
force transducer (WFT) with specialty electronics
platform. It is designed to measure
three forces and three moments during complete
chassis and component road load data
acquisition (RLDA) and other on-road heavy
truck, bus, civilian, and military special vehicle
testing applications. The WFT incorporates
six replaceable three-component heavyduty
load cells. Each load cell
is individually calibrated to
allow sensor replacement
without the need
to recalibrate the
entire system. An integral
identification chip
within each load cell
stores important component
parameters and
prevents data misidentification.
This feature allows data to
be imported into the system’s onboard electronics
upon startup.
